The gingival indexes are reversible, just like the disease itself.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because gingival indexes, which measure the severity of gum disease, can improve or worsen depending on the individual's oral hygiene and treatment. When a person improves their oral hygiene habits and receives appropriate treatment, the gingival indexes can decrease, indicating a reversal of the disease. Conversely, if oral hygiene is neglected or treatment is not sought, the indexes can worsen, indicating a progression of the disease. Therefore, the reversible nature of gingival indexes reflects the reversible nature of gum disease itself.Rate this question:
